Species: P. albiflora. History: Originated by Calot in 1867. DESCRIPTION IN BRIEF: Semi-double, deep purple, late bloomer, fairly good. DESCRIPTION IN DETAIL: Semi-double, not differentiated, yellow stamens mixed all through. Carpelodes not differing from staminodes; secondary flower iri center with very few stamens, and a bunch of small pure white and shiny carpels with red stigmas. Color rosy magenta 4 (169). Size large. Odor pleasant. Foliage medium in size and color, smooth. Comparison: Differs from Louis Van Houtte chiefly by being much larger. One of the best of the much-overdone group of semi-double reds.
